How does Space Weather affect Life on Earth?

Outside of the Earth's magnetic field, radiation from the Sun can hurt satellites. We use these satellites for some radio stations, cell phones and TV stations. We also use those satellites for Earth weather reporting and to provide the Global Positioning
System (your parents' car may use this system to help give directions). This same radiation could be a hazard to astronauts too.

Inside the Earth's magnetic field, space weather has its effects too. Space weather storms can change magnetic signals so that compasses don't work well and even homing pigeons get confused. Space weather storms can also destroy electrical power grids causing the loss of electricity to many people. This size storm doesn't happen very often, but it's important to know when a storm does happen so that we can keep people and things safe.
